Cargèse 2023 School on Subduction Zone Processes
9 October - 13 October
Subduction zones are convergent plate boundaries, where oceanic plates sink into the mantle. They host the largest earthquakes, but also slow slip and tremors. The dynamics of subduction zones, their ability to host episodic tremor and slip, their segmentation depend on several parameters, such as the age and structure of the incoming plate, the geotherm, the presence of fluids, or the thickness and geology of the overriding plate. The factors controlling the time of occurrence and size of the earthquakes, the nature of the link between the slow slip events and the seismic rupture, the role of fluids, the structure and geology of the subduction channel, the rheology of the mantle and its impact on the short-term dynamics of the subduction zones are active areas of research.
The objective of this school is to provide young Earth scientists (Masters, PhD candidates, post-docs) with an overview of the state of the art and current challenges in the study of active subduction. We aim at gathering specialists of different fields, including geodynamic modelers, geologists, seismologists, geodesists, geophysicists to build bridges between these different disciplines and come up with a broad overview of the processes at stake in subduction zones. We also aim at discussing their potential interaction-retroaction effects.
